FIFO versus LIFO

[brendantaylor-res]

Thanks for this useful package!

As I understand it, this queue works like a FIFO (first in first out) buffer. Did you consider an option to make it a LIFO (last in first out) buffer? This would be a useful option in our application since we wish to send the most recent data in the queue first. In the event of a long network outage, the queue could become quite large and waiting to clear the queue before seeing the latest data is not ideal.

Hi. Thanks for the comment.

Yes, this is FIFO. I might make a stack version -- it's a nice idea.
At the moment, I'm too pressed for time. PRs welcome if you're feeling up to it 😄
